| 摘 要： | 根据消石灰改善沥青混合料的性能,分析了消石灰的用量对沥青混合料抵抗水损害的影响以及消石灰的用量与沥青用量之间的关系.通过试验对比证明消石灰的加入可以改善沥青混合料的抗水性能,提高沥青与集料间的粘结强度.消石灰的掺入量在1％～2％之间为宜,消石灰的加入,还须增加相应的沥青用量,提高油石比.

| Abstract: | From the theosefical analysis of the performances of asphalt mixture,it is shown that adding lime hydrate can improve its water resistance,and enhances the bond strength between asphalt and aggregate.Meanwhile,the amount of hydrated lime and the amount of asphalt are discassed.The optimal amount of hydrated lime is 1% to 2%,and it should not be used too much.In addition,if hydrated lime is increased,the asphalt must have a corresponding increase. |

| Keywords: | hydrated lime asphalt mixture water-resistant performance bond strength |
